METAL-BEINFORCING' FtRAME FOR colvonn'rn smiwongunnsl Application med January 24, 1914, Serial Royal 1,051. Renewed January 8,1920. Serial No. 350,244.

To all whom it may concern:

Be it known that I, lVILLra E. FICKLE N, a citizen of the United States, and a res1- dent of Norfolk, county of Norfolk, State of Virginia, have invented certain new and useful Improvements in Metal-Reinforcing Frames for Concrete Structures; and I do hereby declare the following to be a full, clear, and exact description of'theinveu tion, such as to enable any one skilled in the art to make and use the same, reference being had to the accompanying drawings, which form a part of the specification.

My invention relates to metal reinforcements for concrete structures, of that general type embodying side bars or members and transverse members and integral with and connecting the same, but differs from the heretofore known form wherein the structure is of the single-piece expanded metal type, in that my reinforce is composed of two separate bars, and the two bars arranged facing each other, the said bars being connected together by means of braces sheared from the outer edge of each bar in the plane of the bar, with the free end of each brace extended toward opposed bars, said braces being fastened at their free ends to unite said bars rigidly together. i

In order that my invention may be more easily understood, the same is illustrated with reference to the accom an in draw--v ings of which:

Figure 1 is a perspective View of one form of my invention.

Fig. 2 is a modification of the form shown in Fig. l. V

A represents a T bar having a wing or web 10, extending therefrom. B represents a similar bar also having a wing or web 11 extending therefrom.

Out from the web 10 of the bar A longitudinally thereof is a portion 12, whichis extended out from the bar, in a direction substantially perpendicular thereto; many of these portions may be cut from the bar A as seem desirable, the points of integral connection of the extended portions 12 with the web 10 of the bar A being at predetermined intervals. It is to be understood that the length of the extended portions 12 which also is substantially the distance between the bars A and B in the completed structure may be changed to suit variable Specification of Letters latent.

As it Patented oct. 21, 1921.

conditions. Similarly shaped rods or bars 13 are also cut from the-webll of the bar B. Holes 14; and 15 are cut respectively in made in the two webs of such size as to permit-the insertion therein of the ends" of the rods 12 and 13, which ends "are split as illustrated at 16 and hammered down and ammed so as to make a tight joint atthe connection,0r the ends maybe weldedto the web.

In the modification shown in Fig. 2 the cut out portion of the web l2 and 13' in each of the bars A and B is about one half the length of the out out portion 12and 13 of the bars in Fig. 1. These short bars 12 and 13 are extended out of the web and their ends are so constructed that they are made to overlap. They are secured together by rivets or bolts, or may be so constructed,

with ribs or teats as to form small raised portions thereon which will meet for the the stresses at the top and bottom of the beam ;-and the transversely extending mem bers 12, 13, 12, 13 21 and 81 strengthen the web or portion between the top and bottom thereof. Vhen the bars A and B are joined together, a complete frame or unit )f great strength and rigidity, but made up of a relatively small amount of material, is the final result. My improved frame is also capable of use in other concrete constructions, such as partitions, walls, columns, and the like, as will be apparent to those skilled in the art.

The various parts, which assembled, form the entire structure, may be packed separately at the place of manufacture, shipped and assembled at the place ofuse in the way hereinbefore described. Great advantage due to convenience and saving of expense in shipping, results from this capaility of the invention to be made in sepapurpose of electrically welding the ends to rate parts, at the place .of manufacture and tures, comprising a pair of T-bars arranged with their webs toward each other, but spacedapart, stiffening members, out from the edge of each of said webs and extending A straight across to the web of the other, there being holes in each of said webs, and the ends of said stiffening members being split, passed into said holes, and secured in place.

2. A metal reinforcement for concrete structures composed of separately formed bars, each bar having portions sheared from the outer edge of and extended in the plane of the web of thebar and the bars arranged face to face and spaced apart, with the sheared portions of each bar extended toward the opposed bar and secured to hold the bars in their spaced relation. 3. A metal structures, composed of separately formed bars having webs, said bars being arranged with their webs facingeach other, said webs having spacing members out from the same, an end of each spacing member'of'one bar being integral with the web and the other end extended toward the'other' bar' and fastened to the web thereof at points between the integral connections, said integral connections being thus alternately disposed.

In witness whereof I have hereunto set my hand at the city, county and State of New York, this 5th'day of December, 1913.
